# CAD Usage Guide

The CAD module stores transient operational state for dispatch activity,
assignments, dispatch orders, support requests, group profiles, grouped views,
and hydrated UI payloads. CAD state is in-memory and follows the active server
or mission lifecycle.

## Data Model

Most CAD records are flexible JSON objects. The service normalizes important
IDs and returns structured mutation results for higher-level workflows.

Common generated IDs:

- Orders: `cad-order:<sequence>`
- Requests: `cad-request:<sequence>`
- Assignments usually share a task ID or order ID.

## Submit a Support Request

```sqf
private _fields = createHashMapFromArray [
    ["pickup_location", "Grid 123456"],
    ["precedence", "urgent"],
    ["security", "secure"]
];

private _context = createHashMapFromArray [
    ["type", "medevac_9line"],
    ["fields", _fields],
    ["groupId", "alpha"],
    ["groupCallsign", "Alpha 1-1"],
    ["submittedByUid", getPlayerUID player],
    ["submittedByName", name player],
    ["priority", "emergency"],
    ["position", getPosATL player],
    ["createdAt", diag_tickTime]
];

private _result = "forge_server" callExtension ["cad:requests:submit_from_context", [
    toJSON _context
]];
```

Supported priority values are `routine`, `priority`, and `emergency`. Unknown
values normalize to `priority`.

## Create a Dispatch Order

```sqf
private _context = createHashMapFromArray [
    ["assigneeGroupId", "bravo"],
    ["assigneeGroupCallsign", "Bravo 1-1"],
    ["targetGroupId", "alpha"],
    ["targetGroupCallsign", "Alpha 1-1"],
    ["targetPosition", getPosATL player],
    ["createdByUid", getPlayerUID player],
    ["createdByName", name player],
    ["requestId", "cad-request:1"],
    ["requestType", "logreq"],
    ["requestTitle", "LOGREQ | Alpha 1-1"],
    ["requestSummary", "Ammo resupply requested"],
    ["requestFields", createHashMap],
    ["note", "Support Alpha 1-1 at current position."],
    ["priority", "priority"],
    ["createdAt", diag_tickTime]
];

private _result = "forge_server" callExtension ["cad:orders:create_from_context", [
    toJSON _context
]];
```

## Assignment Workflow

Task contracts have two separate phases. Dispatch assignment reserves a
contract for a group and sets the CAD assignment state to `assigned`, but it
does not accept or start the task. The assigned group leader must acknowledge
the assignment before task ownership is bound and task logic starts. If the
leader declines, the CAD assignment is removed and the contract returns to the
open board. Task status follows the same lifecycle: `available` on creation,
`assigned` after dispatch assignment, and `active` after acknowledgement.

```sqf
private _assignment = createHashMapFromArray [
    ["groupId", "bravo"],
    ["assigneeGroupCallsign", "Bravo 1-1"],
    ["assignedByUid", getPlayerUID player],
    ["assignedByName", name player],
    ["assignedAt", diag_tickTime],
    ["state", "assigned"]
];

"forge_server" callExtension ["cad:assignments:assign", [
    "task-123",
    toJSON _assignment
]];

private _ack = createHashMapFromArray [
    ["state", "acknowledged"],
    ["acknowledgedByUid", getPlayerUID player],
    ["acknowledgedAt", diag_tickTime]
];

"forge_server" callExtension ["cad:assignments:acknowledge", [
    "task-123",
    toJSON _ack
]];
```

## Hydrate the CAD UI

```sqf
private _session = createHashMapFromArray [
    ["uid", getPlayerUID player],
    ["orgId", "default"],
    ["isDispatcher", true],
    ["groupId", "alpha"],
    ["isLeader", true]
];

private _seed = createHashMapFromArray [
    ["groups", _liveGroups],
    ["activeTasks", _activeTasks],
    ["session", _session]
];

private _result = "forge_server" callExtension ["cad:view:hydrate", [toJSON _seed]];
```

## Error Handling

```sqf
private _payload = _result select 0;
if (_payload find "Error:" == 0) exitWith {
    systemChat format ["CAD error: %1", _payload];
};
```
